SWITCH-OPERATING DEVICE.

remesa.

To all whom t may concern:

Be it known that I, MATTHEW 17V. DavisoN, a citizen of the UnitedStates, residing at Dubois, in the county of Clearfield and State ofPennsylvania, have invented certain new and useful Improvements inSwitch-Operating Devices, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to switch operating devices and has for itsobject to provide a very simple device which is especially devised foruse on street railways whereby the switches may be opened or closed fromthe platform of the car by the motorman.

Another object of the invention resides in `the provision of movablemeans arranged between the track rails and connected to the switchpoints, said means being adapted for actuation by means arranged on thecar and operated by the motorman whereby the switch may be opened orclosed.

lVith the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a plan view of a switchprovided with my improved throwing mechanism; Fig. 2 is a section takenon the line 2 2 of Fig. 1 showing actuating means carried by the carabout to throw the switch points; Fig. 3 is a section taken on the line3 3 of Fig. 1; and Fig. 4 is a detail perspective view of the switchpoints, the connecting bar, and the pivoted throwing bars.

Referring more particularly to the drawings 5 designates the track railsand 6 the switch points which are arranged in the track in the usualmanner. These rails and switch points are mounted upon ties 7 or may besupported in any other desired manner.

As shown in the drawing the switch is open so that the car will moveover the side track rails. A bed plate 8 is arranged upon the rail tiesinside of each of the rails and over these bed plates the switch pointsare adapted to move. Each of the switch points is formed with an ear 6to which the ends of the connecting bar 9 are pivotally connected asindicated at 10, said connecting bar extending beneath openings 8 formedin the bed plates 8.

11 is secured upon the rail supporting ties between the switch pointsand upon this base plate the throwing bars 12 are pivoted, at one oftheir ends as shown at 13. The other ends of these bars are movable overthe openings 14 in the base plate and bolts 15 extend through theseopenings and pivotally connect the bars 12 with the connecting bar 9which connects the switch points 6. The bar 9 which connects the switchpoints is formed in two sections which are pivotally connected at theirinner ends as indicated at 9. Thus in the pivotal movement of the bars12 the sections of the connecting bar 9 will have a slight relativemovement.

Upon each end of the platform of the car C, the vertically movableactuating rods 17 are mounted. These rods move in the sleeves 18 securedabove and below the platform and have coiled springs 19, arrangedthereon which normally act to force the rods upwardly. Upon the upperends of the rods the foot plates 20 are secured which are adapted to beengaged by the foot of the motorman to depress the rods.

In the operation of the device, when the switch is open as shown in Fig.1, the motorman depresses the proper rod so that it will engage one edgeof one of the throwing bars 12 and force said bar transversely betweenthe rails, thus also throwing the switch points through the niedium ofthe bar 9 which connects the same. In this manner the switch may beclosed without requiring the motorman to dismount from the car so thatthe car will pass over the switch rails. In order to open the switch theother of the rods 17 is depressed and the switch points moved in theopposite direction.

From the above it will be seen that the device may be easily and Quicklyoperated and considerable time saved in the throwing of the switches.The device is comparatively simple and very eihcient in practicaloperation. It may be readily installed in the present system of railwayconstruction at small cost.

While I have above described the preferred construction and arrangementof the various parts, it will be understood that the device issusceptible of considerable modification without departing from theessential feature or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is In combinationwith the fixed rollers and movable pivoted switch points of a railwayswitch, said switch points being provided at their bases with laterallyeX- tending horizontal ears, bed plates on which the switch pointsoperate and provided with openings to receive the ears of the switchlpoints and in which said ears move, a base plate between the bed platesand also having openings in line with those of the base plates, a barpivotally connected to the under side of the ears of the switch points,

and formed in two sections pivotally connected together, and throw barseach pivotally connected at one end of the bed plate Y MATTHEW w.DAvisoN.
